Description

Technical Field

[0001] The utility model relates to the technical field of O-rings, and specifically, to an O-ring that prevents falling off. Background Technique

[0002] O-ring seals are suitable for being installed on various mechanical equipment and play a sealing role in a static or moving state under specified temperature, pressure, and different liquid and gas media. A large number of various types of sealing elements are widely used in machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and various types of instruments and meters.

[0003] For example, Chinese Patent CN216200433U discloses a rubber O-ring that is convenient to adjust, including an outer layer. A sandwich layer is arranged inside the outer layer, and an inner layer is arranged inside the sandwich layer. A first card slot is opened on the inner side of the outer layer, a first snap ring is arranged on the outer side of the sandwich layer, a second card slot is opened on the inner side of the sandwich layer, and a second snap ring is arranged on the outer side of the inner layer. It can be connected to sandwich layers with different outer diameters, realizing the thickness adjustment of the O-ring. However, during the long-term use of the O-ring, especially in dynamic sealing applications (such as rotating equipment like pumps and compressors), it will cause wear on the inner wall of the O-ring, accelerating the aging of the rubber material, thus directly reducing the performance and service life of the O-ring.

[0004] Regarding the problems in the related art, no effective solutions have been proposed yet. Content of the Utility Model

[0005] Regarding the problems in the related art, the utility model proposes an O-ring that prevents falling off to overcome the above-mentioned technical problems existing in the existing related art.

[0006] To this end, the specific technical solution adopted by the utility model is as follows:

[0007] An O-ring that prevents falling off, including an O-ring body. A plurality of anti-slip ridges are arranged at both the top end and the bottom end of the O-ring body. Grooves are opened at both the top end and the bottom end of the inner wall of the O-ring body. A skirt is arranged on one side of the groove. Sealing components are symmetrically arranged in the middle of the inner wall of the O-ring body; a plurality of anti-falling-off grooves are symmetrically opened on the outer side of the O-ring body. A plurality of chambers are opened inside the O-ring body, and a spring is arranged inside the chamber; an elastic skeleton is embedded inside the O-ring body and the skirt.

[0008] Furthermore, in order to increase the friction between the O-ring and the installation surface and effectively prevent the O-ring from falling off or sliding during installation and use, the cross-section of the anti-slip ridge is a semi-circular structure, and a plurality of anti-slip ridges are evenly arranged.

[0009] Furthermore, in order to provide better support and stability when the O-ring is under pressure, and also to help prevent leakage of liquid or gas from the inner edge of the O-ring, while under the action of the elastic skeleton, the tightness between the O-ring and the mounting surface is ensured, improving the reliability of the seal. The cross-section of the skirt is an annular structure, and the size of the cross-section of the skirt gradually increases along the direction away from the sealing assembly. The cross-section of the elastic skeleton is a V-shaped structure.

[0010] Furthermore, in order to improve the sealing performance of the O-ring, the inclined design enables the sealing lip to better fit the mounting surface when under pressure, forming an effective seal. The sealing assembly consists of several sealing lips connected to the inner wall of the O-ring body, and the sealing lips are inclined.

[0011] Furthermore, in order to prevent the O-ring from falling off during use, when the O-ring is under pressure, by squeezing the anti-falling groove, the air inside the anti-falling groove is discharged and a negative pressure is generated, making the O-ring adsorb more tightly on the mounting surface and preventing the O-ring from falling off during use. Several anti-falling grooves are arranged in an equidistant annular pattern, and the cross-section of the anti-falling groove is a disc-shaped structure.

[0012] Furthermore, in order to enable the O-ring to better adapt to different mounting surfaces and pressure changes during installation and use, providing a continuous sealing effect. At the same time, the cross-shaped arrangement of the springs also helps to evenly distribute the pressure and improve the service life of the O-ring. The ends of the springs are fixedly connected to the inner wall of the chamber, and adjacent pairs of springs are arranged in a cross shape.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. The structure of the present utility model is reasonable and reliable. The anti-falling O-ring comprehensively utilizes a variety of structural elements, which not only improves the sealing performance but also significantly enhances the stability and durability of the O-ring, and is very suitable for use in high-pressure or extreme environments.

[0015] 2. By setting the anti-slip ridges, the friction between the O-ring and the mounting surface can be increased, effectively preventing the O-ring from falling off or sliding during installation and use.

[0016] 3. By setting the skirt, the sealing assembly and the elastic skeleton, better support and stability can be provided when the O-ring is under pressure, and it also helps to prevent leakage of liquid or gas from the inner edge of the O-ring. At the same time, under the action of the elastic skeleton, the tightness between the O-ring and the mounting surface is ensured, improving the reliability of the seal. The inclined design enables the sealing lip to better fit the mounting surface when under pressure, forming an effective seal.

[0017] 4. By setting the anti - shedding groove, it is possible to prevent the O - ring from falling off during use. When the O - ring is compressed, by squeezing the anti - shedding groove, the air inside the anti - shedding groove is discharged and a negative pressure is generated, making the O - ring adsorbed more tightly on the installation surface and avoiding the O - ring from falling off during use.

[0018] 5. By setting the spring, the O - ring can better adapt to different installation surfaces and pressure changes during installation and use, providing a continuous sealing effect. At the same time, the cross - shaped arrangement of the spring also helps to evenly distribute the pressure and improve the service life of the O - ring. BRIEF DESCRIPTION OF THE DRAWINGS

A plurality of chambers 7 are formed inside the O - ring body 1, and a spring 8 is provided inside the chamber 7. In addition, in specific applications, the above - mentioned spring 8 is set as a compression spring; An elastic skeleton 9 is embedded inside the O - ring body 1 and the skirt 4.

[0028] In addition, it should be noted that the material of the elastic skeleton 9 is any one of stainless steel, spring steel, aluminum alloy, and elastomeric materials, which is mainly used to provide additional support and stability, ensure that the O - ring is in close contact with the installation surface, and thus improve the sealing performance.

[0029] By virtue of the above - mentioned technical solution of the present utility model, the structure of the present utility model is reasonable and reliable. The anti - shedding O - ring comprehensively uses a variety of structural elements, while improving the sealing performance, significantly enhancing the stability and durability of the O - ring, and is very suitable for use in high - pressure or extreme environments.

[0030] In one embodiment, for the above - mentioned anti - slip ridges, the cross - section of the anti - slip ridge 2 is a semi - circular structure, and a plurality of anti - slip ridges 2 are arranged evenly, so as to improve the friction between the O - ring and the installation surface, and effectively prevent the O - ring from falling off or sliding during installation and use.

[0031] In one embodiment, for the above - mentioned skirt 4, sealing components 5 and elastic skeleton 9, the cross - section of the skirt 4 is an annular structure, and the size of the cross - section of the skirt 4 gradually increases along the direction away from the sealing component 5; The sealing component 5 is composed of a plurality of sealing lips 501 connected to the inner wall of the O - ring body 1. In addition, in specific applications, the number of the above - mentioned sealing lips 501 is at least set to 2, and the sealing lips 501 are inclined. The cross - section of the elastic skeleton 9 is a V - shaped structure, so as to provide better support and stability when the O - ring is under pressure, and at the same time help to prevent liquid or gas from leaking from the inner edge of the O - ring. At the same time, under the action of the elastic skeleton 9, the tightness between the O - ring and the installation surface is ensured, and the reliability of the seal is improved. The inclined design enables the sealing lips 501 to better fit the installation surface when under pressure, forming an effective seal.

[0032] In one embodiment, for the above anti - shedding groove 6, a plurality of anti - shedding grooves 6 are arranged in an equidistant circular pattern, and the cross - section of the anti - shedding groove 6 is a disc - shaped structure. This can prevent the O - ring from falling off during use.

[0034] To facilitate the understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in the actual process will be described in detail below.

[0035] In actual application, by installing the anti - shedding O - ring at the sealing installation surface required by the product, the anti - slip protrusions 2 can increase the friction between the O - ring and the installation surface. The skirt 4, the sealing assembly 5 and the elastic skeleton 9 can provide better support and stability when the O - ring is under pressure, and ensure the tightness between the O - ring and the installation surface, improving the reliability of the seal. The anti - shedding groove 6 enables the O - ring to squeeze the anti - shedding groove when under pressure, discharging the air inside the anti - shedding groove and generating a negative pressure, so that the O - ring is adsorbed more tightly on the installation surface, avoiding falling off during use. The end of the spring is fixedly connected to the inner wall of the chamber, and two adjacent groups of springs are arranged in a cross - shape, enabling the O - ring to better adapt to different installation surfaces and pressure changes during installation and use, providing a continuous sealing effect, and helping to evenly distribute the pressure.

[0036] In summary, by means of the above technical solutions of the present utility model, the structure of the present utility model is reasonable and reliable. The anti-detachment O-ring comprehensively uses a variety of structural elements, which not only improves the sealing performance, but also significantly enhances the stability and durability of the O-ring, and is very suitable for use in high-pressure or extreme environments. By providing the anti-slip ridges 2, the friction between the O-ring and the installation surface can be increased, effectively preventing the O-ring from detaching or sliding during installation and use. By providing the skirt 4, the sealing assembly 5 and the elastic skeleton 9, better support and stability can be provided when the O-ring is under pressure, and it also helps to prevent liquid or gas from leaking from the inner edge of the O-ring.

The inclined design enables the sealing lip 501 to better fit the installation surface under pressure, forming an effective seal. By providing the anti-detachment groove 6, the O-ring can be prevented from detaching during use. When the O-ring is under pressure, the air inside the anti-detachment groove 6 is squeezed out, generating a negative pressure, so that the O-ring is more tightly adsorbed on the installation surface, avoiding the O-ring from detaching during use. By providing the spring 8, the O-ring can better adapt to different installation surfaces and pressure changes during installation and use, providing a continuous sealing effect. At the same time, the cross-shaped arrangement of the spring 8 also helps to evenly distribute the pressure and improve the service life of the O-ring.
